Forked from Melting Data for Multiple Lines

This visualization displays global population trends over time as a multi-line chart, with each line representing a different country and colored via `d3.scaleOrdinal`. Users hover over the chart to select a year, which triggers a vertical line and updates the visualization through a `mousemove` event using `d3.pointer` and `xScale.invert`. The chart renders with SVG, uses `d3.scaleTime` and `d3.scaleLinear` for axes, and generates paths with `d3.line` and `d3.curveBasis`. Data comes from UN population estimates processed through `d3.csv` and `topojson`.

Selecting a Year on a Line Chart

This visualization displays population trends over time for global regions, with a vertical line marking the currently selected year. Users can hover over the chart to change the selection, which updates the highlighted year. The chart uses D3 v5 with SVG rendering, employing scales like `scaleTime` and `scaleLinear` for axes, and `d3.line` with `curveBasis` for smooth paths. Data comes from UN population estimates and medium variant projections, processed via `d3.csv` and `d3.nest`. A custom color legend shows region names, and the selection uses mouse events to update the year.

Selecting a Year on a Line Chart

This visualization shows population trends over time for global regions, with a vertical line marking the currently selected year. Users can move the mouse across the chart to select a different year, updating the line’s position. The line chart uses d3.scaleTime, d3.scaleLinear, d3.line, and d3.curveBasis for rendering, while d3.nest groups data by region. A d3.Ordinal scale with schemeCategory10 colors each line, and a custom colorLegend component displays the categories. Data comes from UN population estimates and medium variant projections, processed with d3.csv and d3.timeParse.

Selecting a Year on a Line Chart

This visualization displays population trends over time for various world regions using a line chart, rendered with SVG. Users can hover over the chart to select a specific year, which updates a vertical black line to mark that point in time. Built with D3 v5, the code utilizes `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` for axes, `line` with `curveBasis` for the paths, and `nest` to group data by region. The color legend is created using `scaleOrdinal` with `schemeCategory10`. Data comes from UN population estimates.

Selecting a Year on a Line Chart

This visualization shows population trends over time for world regions, with a vertical black line marking the currently selected year. Moving the mouse across the chart updates the selected year and repositions the line. The code uses D3 v6 with SVG rendering, employing `scaleTime`, `scaleLinear`, `line` with `curveBasis`, and `axisBottom`/`axisLeft` for axes. Data comes from UN population estimates CSV files, melted into tidy format for visualization. The color legend is built with a custom `colorLegend` function using `scaleOrdinal` and `schemeCategory10`.

Selecting a Year on a Line Chart

This line chart visualizes population trends over time by region, sourced from UN population estimates and medium-variant projections (1950–2100). A vertical line highlights the currently selected year, which users change by hovering anywhere on the chart, triggering a re-render via `setSelectedYear`. The chart uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` with `d3.curveBasis` for smooth paths, and a categorical color legend built from `d3.schemeCategory10`. A semi-transparent rectangle captures `mousemove` events to invert the mouse position back to a date with `xScale.invert`.

Selecting a Year on a Line Chart

This line chart displays global population trends by region from 1950 to 2100, with a draggable mouse interaction that updates a selected year to highlight a specific time point. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `nest` to organize data, while a custom `lineChart` module renders SVG paths with `d3.line` and `curveBasis`. A brush-like `rect` element captures `mousemove` events to invert the x-scale and trigger year selection. Data comes from UN population estimates, with a color legend built via a reusable `colorLegend` function.

Selecting a year on a line chart

This visualization shows world population trends over time across regions, with a vertical line marking a selected year. Users can move their mouse across the chart to update the selected year, which highlights the corresponding point in time. The code uses d3.line, d3.scaleTime, d3.scaleLinear, and d3.axisBottom to render the SVG line chart, while d3.mouse captures interactive hover events. Population data comes from UN estimates (1950-2014) and medium variant projections (2015-2100), processed via d3.csv and d3.nest.

Selecting a Year on a Line Chart

This line chart displays population trends over time for global regions, with a draggable vertical line enabling year selection. The chart updates dynamically as users hover, highlighting the selected year across all series. Built with D3 v5, it uses `nest()` for data grouping, `scaleTime` and `scaleLinear` for axes, and `line()` with `curveBasis` for smooth paths. Data comes from UN population estimates (1950-2100), with a color legend and axis labels rendered as SVG elements.
